When I double click on a .bsi or a .avi file in the windows explorer (which are both registered for bsplayer), the Player will start up for a moment, but when attempting to play, it will quit to desktop without any message.
When I open a file via the bsplayer "Open..."-Dialog, it works fine.

The strange thing is, this does not happen all the time; from time to time the double-click method works as intended, with no reproducable pattern.

I'm using the latest nightly build 200307061027, but the problem occured for me already in build 499.
Before I was using 494 without this problem, 496, which I installed now also seems to work fine.
